The first settlers were grantees from Hampton, among whom were at least sixteen Moultons, giving the town its name. Colonel Jonathan Moulton was considered to be one of the richest men in the province at the start of the American Revolution. Moultonborough was chartered in 1763 by Colonial Governor Benning Wentworth, and at the time was described as being near the "Winnepisseoky Pond." It would be incorporated in 1777.

Moultonborough is home to the "Castle in the Clouds," an estate set in the Ossipee Mountains. Thomas Gustave Plant made a fortune manufacturing shoes, bought 6,300 acres (25 km2) and hired the Boston architectural firm of J. Williams Beal & Sons to design "Lucknow," a stone mansion built between 1913 and 1914. The property, with sweeping views of Lake Winnipesaukee, is a popular tourist attraction.
